MACHINE FOR USE IN TRIMMING SHRLUBBERY.

lApplication iled January 23, 1928. Serial No. 248,930.

This invention relates vto implements for use in connection with the care of shrubbery, and gardening, and it has particular reference to an improved, electrically operated hedge trimming apparatus, the principal object of which resides in the provision of apparatus as designated byv which to reduce to provided-with means bywhich it-`may be adjusted according to the density, or coarseness of the shrubbery uponwhich it is operated.

With the foregoingl objects as paramount, the invention has further o`b]ects, as well as vcertain salient features of construction and operation of parts, to become manifest as the description proceeds taken in connection with the accompanying drawings wherein Figure 1 represents a perspective view of an improved hedge trimming apparatus constructed according to the present inventlon, and

Figure 2 is a side elevational 4view of. the invention. l

Continuin now more in .detail with the erably of the type employed in operating Ventilating fans, since it is important that the apparatus as a whole be very light in weight in order that it may be expeditiously manipulated in operation. To one side of the motor, which is the front of the device, is aiiixed' a handle 2, andconvemently applied at the opposite side is another handle 3. These handles are arranged 1n such a manner as to enable the operator to hold the machine in operative position with minimum eli'ort.

Aiiixed to the underside of the motor is a metal late 4., held by screws 5, which plate is so ormed as to return beneath the portion 4 and form a guard 6, having a plurality of forwardly directed fingers and to engage the shrubbery as the machine is urged /forward. A

The niotor. drive shaft 8 is directed downwardly as shown in Figure 2 and has aiiixed thereto by set screw 9, a iy wheel 10, proportionately weighted as to maintain uniform motion of the circular saw 11, as imparted thereto by the motor 1, when the same cuts into stubborn or tough shrubbery. The guard 6 is capable of being adjusted toward and away from the saw 11 by threaded studs 12, provided with exterior nuts 13,v and lock nuts 14, in the event it becomes necessary in trimming shrubbery of varying density.

Electrical current is supplied to the motor by way of wires 15, through fuse 16.

Itis especially pointed out that the invention is particularlyuseful in pruning hedges of considerable length, the invention obviously saving time and labor due to its automatic operation and the ease by which it may be manipulated. Moreover, such use of the invention obviously enables the operator to obtain a more symmetrical appearance of the `hedge or shrubbery over which the same is operated, and with greater speed, especially due to the Ycutting radius of the saw 11 and span of the guard 6.

In operation, the operator grips the handle 3 in one hand and the handle 2 in the other, and having previously arrived at the desired design to be carried'out, the machine is run over the surface, severing the ends, of the protruding shrubbery, until the hedge is properly shaped.

Obviously, the invention described is capable of some changes and modifications and such changes and modifications construed to be in keeping with the spirit of the invention may be made without departing from the scope of the appended claims therefor.

I claim:

1. A shrubbery trimming device including a substantially U-shaped resilient metal plate, a motor secured to the outer face of one side of the plate and having its shaft extending through said side, the other side of the plate having its free end formed with guard fingers which extend beyond the free en'd of the rst named side, a cutter*r disposed adjacent to the inner face of the second named -side and mounted on the motor shaft, a iy wheel also mounted on the motor shaft bethereon to increase or decrease the distance between the plate sides and thereby the relation of the second named side of the plate to the cutter.

2. A shrubbery trimming device including a substantially U-shaped resilient metal plate,

tweenthe sides of the plate and engaged a motor secured to the outer face of one side of the plate and having its shaft extending through said side, the other side of the plate having its free end formed with guard ngers which extend beyond the free end of the lirst named side, a cutter disposed adjacent to the inner face of the second named side and mounted on the motor shaft, a iy Wheel also mounted on the motor shaft between the sides of the plate, and means connected to each of the sides of the plate to increase or 'decrease the distance between the plate sides and thereby the relation of the second named side of the plate to the cutter.

3. A shrubbery trimming devicefincluding a substantially U-shaped resilient metal plate, a motor secured to the outer face of one side of the plate and having its shaft extending through said side, the other side of the plate having its free end formed with guard fingers which extend beyond the free oud of the first named side, a cutter disposed adjacent to the inner face ofthe second named side and mounted on the motor shaft, and means connected to each of the sides of the plate to increase or decrease the distance between the plate sides and thereby the relation of the second named side of the plate to the cutter.

In testimony whereof I aix my signature.
